Write the equation of the line that passes through the points (3, 6) and (5, 18) using function notation.
andreev551 [17]

Answer:

f(x) = 6x -12

Step-by-step explanation:

We must write the function of the line in the form f (x) = mx + b

First calculate the slope m

m =\frac{y_2-y_1}{x_2-x_1}

y_2 = 18\\y_1 =6\\x_2=5\\x_1=3

m= \frac{18-6}{5-3} = 6

Then

f(x) = 6x +b

To have b replaced a point in the function

f(3)=6 = 6(3) +b\\\\6-18= b\\\\b=-12

Finally the function is

f(x) = 6x -12

When calculating simple interest, what must you do if you want to invest for months or weeks instead of years?
iVinArrow [24]

The formula for calculating the simple interest is given by

I=Prt

Here, P = Principle amount

r = annual interest rate in decimal

t = time in years.

Now, if we invest for months or week then in order to find the simple interest, we must convert the units in years.

Therefore, d is the correct option.

d) Interest rates are annual, so you must convert the units into years.

Benito spent $1837 to operate his car last year. Some of these expenses are listed on the table below:
Dmitry_Shevchenko [17]

Answer:

$0.085 per mile or 8.5 cent per mile

Step-by-step explanation:

We know:

Total expenses = $1837

Gasoline expense = Total expenses - other expenses

= 1837 - 972 - 114 - 105 = $646

Benito drove in total of: 7600 miles

Cost of gasoline per mile = Money spent for gasoline / total miles

= $646 / 7600

= $0.085 per mile or 8.5 cent per mile

Hope this helped :3
